Referring to the drawings: Figure lis a view chiefly 'in VVverticalsection, showing 25 portions of the spring and valve stem or 'rod andillustrating my invention applied thereto, some parts being bfken awayand some parts being shown full; Fig. 2 is a transverse section taken onthe line approximately on the line :1:3 :1:3 of Fig. 1;

The valve stem is indicated vby the iiu- As a means for causing thespring to re-act against the valve stem, it has been customai'y toprovide a socalled spring .cap for engagement with one end of the springand My invention iovides an extremely simple and highly e cient devicefor detachably r locking or anchoring the spring cap to the valve stemand for permitting quick detachment thereof from the stein whenever dc-'sired. The spring cap 3 has an axial per- `lfora'tion, adapting it tobe slipped freely .over the valve stem and it is preferably pro- 56turned edge, forming a concave seat, within. I

compression of the stein, the valve s tein is i provided with a notchpreferablyin the form of an angular groove 4. lA 'retainer or lock.plate 5, preferably of oblongvferni, is Y formed ywith an elongatedslot, oneextiein- -ity 6 of which is of suiicient diameter to permit thesaid retainer to be slipped over i and on to the valve stem. The otherex- 60 tremity or portions 7 of the saidv slot is of such width that itcannot be passe'd on to j the full diameter ofthe valve stein," but mabe slid int-o interlocking engagement wit the lock groove 4. At that endwhich is adjacent to the large end 6,' the retainer 5 is 'provided witha laterally bent or extended lock lug or .fiange 3, which when theretainer and spring cap are in working position, as shown in Fig. l,engages the rim of said cap so that the cap serves in turn to hold theretainer in working position. Y When it is desired to remove the spring`cap from the valve stem or to move the same on the valve stem so as torelieve the spring from tension. it is necessary first to force thevspring cap far enough away from the retainer to permit the latter to bemoved radially inward until the large extremity 6 of its slot is broughtinto registration with the valve stein. whereupon the said retainerinaybe slipped oil of the stem of the said spring cap and the said sprinv'ycap will than be free for moveinent,also,'ot from-the valve stem.

The device above described, while extremely simple and of small cost,has in practice been found highly practical for tlie Y purposes hadview. By use thereof, it 1s niade an easy matter to apply springs tovalve -stems or rods and to remove said springs therefrom. The deviceis, however, capabe of general use, wherever it 1s desirable to locka'spring cap or similar member of a stein or rod. Attention is, also,called to the fact that the construction of the spring cap and of theretainer are such that both may be stamped from pieces of sheet metaland neither requires boring.
